[2025-10-01T20:55:26.739519] [PI reasoning] **Identifying enzyme cofactors**

I’m looking to determine which enzyme doesn’t use thiamine (vitamin B1) as a cofactor. I know that thiamine pyrophosphate (TPP) is essential for enzymes like pyruvate dehydrogenase and transketolase. However, succinate dehydrogenase uses FAD, related to riboflavin, instead. So, I’ll conclude that the answer is C. To support my reasoning, I might need to look up some evidence through a quick search.
